power: supply: rk817: Change rk817_chg_cur_to_reg to int

Change return value of rk817_chg_cur_to_reg from u8 to int. If the
function fails to find a suitable value it returns a -EINVAL, but
defined as a u8 it would not return correctly. Additionally, change
defined variable that stores return value from u8 to int.
